Little x’es, noise and all the stuff you like. Dark like a Monday, with a hint of blue.

This light blue background pattern is quite pleasing to the eye, it consists of a tiny rough grid pattern, which is seamless by design. That's it, if you like the color, you can use this seamless pattern in a web design without making any further modifications to it.

A repeating background of beige (or is it more vanilla yellow) textured stripes. One more background with stripes.
